Description

Technical Field

[0001] The invention belongs to the technical field of lamps, and in particular to a lamp with high lamp bead utilization rate. Background Art

[0002] The optical angle of existing LED lamps is generally single. There are two main ways to change the optical angle. The first is to manually rotate or replace lenses with different optical angles. This method will increase labor costs and reduce product reliability. In addition, if you want to change the optical angle of the lamp, you need to prepare several optical products, which puts a lot of pressure on the inventory and high storage and transportation costs. The second is to change the optical angle mechanically by adding a mechanical structure. This method makes the product structure complicated. Not only must an additional waterproof structure be added, which increases a lot of costs, but the product structure is complicated and the durability is insufficient. According to statistics, the lamp bead utilization rate of existing LED lamp products is between 50% and 60%, and there is still a lot of room for improvement. Summary of the invention

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] Provide a lamp with high lamp bead utilization rate, such as Figure 1 As shown, including:

[0032] The lens group 1 includes a plurality of lenses 11 arranged in sequence, each lens having at least one or more different light-emitting angles. The light-emitting angle of the lens represents the irradiation angle of the LED light after passing through the lens. The standard irradiation angle of the LED is 20 to 45 degrees, but secondary dimming can be performed by stacking lenses to expand the irradiation range of the LED to meet the needs of different application scenarios. The lens is designed to have different irradiation angles through optical simulation. In a preferred embodiment, Figure 2 , 3 As shown, each lens is designed to have three light types, namely, light-emitting angle A (7), light-emitting angle B (8) and light-emitting angle C (9).

[0033] LED lamp beads 2, LED lamp beads are arranged under the lens in groups of at least two; in each group of LED lamp beads, at least two color temperatures of LED lamp beads are included. The color temperature ranges from 2700K to 6500K; preferably, the color temperature includes five types of 2700K, 3000K, 4000K, 5000K and 6500K. For example, under the above three light types, two color temperature lamp beads are arranged: LED lamp bead D and LED lamp bead E. The distribution of the lamp beads is precisely positioned after optical simulation.

[0034] Controller 3, the controller is used to control the power of the LED lamp beads. Further, the controller includes a dial switch for easy adjustment. Preferably, as Figure 4 As shown, the controller includes a dial switch for adjusting the LED lamp bead power, selecting the LED lamp bead color temperature, and selecting the lighting angle of the lamp.

[0035] When the LED lamp beads are lit, the controller divides all the LED lamp beads into a preset number of groups according to the preset LED lamp bead utilization rate, and according to the different brightness and power of the LED lamp beads in each group, the lamp has at least two overall luminous angles different from the luminous angle.

[0036] Specifically, when the lamp is in use, the corresponding power, color temperature, and angle programs are pre-set in the MCU on the controller. The corresponding LED and the corresponding light type LED will light up by adjusting the gear of the dip switch through the dip switch; according to the pre-set duty cycle of the current of each lamp bead, for example, the brightness of some lamp beads will reach 80%, and the brightness of some lamp beads will reach 20%, and the arrangement and combination control is performed to achieve the required lighting effect. Taking the application scenario of industrial and mining lamps as an example, the optical requirements of industrial and mining lamps usually use three types of 60° / 90° / 110°, and the overall luminous angle of the lamp will also support 60 degrees, 90 degrees, and 110 degrees, but the overall luminous angle range is not limited to this, and the range can reach 40~140°.

[0037] A three-group arrangement of lamp beads Figure 5 As shown, there are three types of light baffles with luminous angles of 56 degrees, 90 degrees and 126 degrees. Each light baffle has a diameter of 10mm, with a total of 430 light baffles, which are arranged in 9 circles from small to large and from inside to outside. When the lamp beads are lit, light baffles at different angles and positions can achieve different powers or different color temperatures according to the software, thus forming an overall lighting effect that meets the needs.

[0038] In one implementation, the preset LED lamp bead utilization rate is 100%; all LED lamp beads are divided into two groups: a first group and a second group, each group has 50% of the LED lamp beads, and the group to which each lamp bead is divided is also predetermined by the software program. The first group and the second group are mixed according to a preset luminous flux ratio, and the preset luminous flux includes but is not limited to 3:1, 4:6, and 1:3. After mixing, the lamp has an overall luminous angle that is consistent with the preset luminous flux ratio and different from the luminous angle.

[0039] For example, suppose the first group includes two types of LED lamp beads with a light-emitting angle of 56 degrees and a light-emitting angle of 90 degrees, and each accounts for 50%; the second group includes LED lamp beads with a light-emitting angle of 126 degrees; after the first group and the second group are mixed according to 3:1, 4:6, and 1:3, the overall light-emitting angles of the lamp are 68 degrees, 92 degrees, and 108 degrees, respectively. Among them, when mixing light, not only one type of lamp bead will be lit, the other type of lamp bead will also be slightly bright, the ratio is 3000K color temperature lamp bead reaches 95% brightness, 5000K color temperature lamp bead reaches 5% brightness, or the ratio is 3000K color temperature lamp bead reaches 5% brightness, 5000K color temperature lamp bead reaches 95% brightness, or 4000K lamp bead reaches 50% brightness; that is, no matter at what angle the light is mixed, all lamp beads will be lit.

[0040] It is understandable that the LED lamp beads are not limited to being divided into the first group and the second group, but may be other number of groups, and the number and types of the overall light emitting angles are not limited to the above three. Through the adjustable duty cycle technology, the lamp bead utilization rate of the present invention can reach 100%.

[0041] Furthermore, in one implementation, Figure 6 As shown, the lamp also includes:

[0042] An aluminum substrate 3, the aluminum substrate is arranged below the lens group, and the LED is arranged on the aluminum substrate and upwardly corresponds to the lens;

[0043] Radiator 4, the radiator is arranged below the aluminum substrate; the controller is arranged below the radiator;

[0044] Power supply 6, the power supply is connected to the controller.

[0045] Compared with existing mining lamps (which require three lenses, three aluminum substrates, and three power supplies), this structure has lower costs and reduces many SKUs. At the same time, users can change the light type according to on-site conditions.

[0046] The above is an explanation of the lamp with high lamp bead utilization rate of the present invention, which is used to help understand the present invention; however, the implementation mode of the present invention is not limited to the above-mentioned embodiments, and any changes, modifications, substitutions, combinations, and simplifications made without departing from the principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
