Embodiment 1

[0025] see figure 1 , the embodiment of the present invention provides a lens unit 300 , and the lens unit 300 includes a flood lens 310 and a condenser lens 320 .

[0026] In the embodiment of the present invention, the floodlight lens 310 and the condenser lens 320 are integrally arranged, for example, they can be integrally arranged by means of bonding, screwing, insert injection molding, etc., the floodlight lens 310 and the condenser lens 320 adopts the same material or different materials, for example, the flood lens 310 and the condenser lens 320 can use polymethyl methacrylate material or polycarbonate material, in the above way, when the light passes through the flood lens 310 When combined with the condensing lens 320, the light is refracted by the flood lens 310 and the condensing lens 320 to form flood light and condensed light respectively, and the light rays do not overlap substantially. The structure is simple, the cost is low, and the utilization rate of the li...

Embodiment 2

[0029] see figure 2 , the embodiment of the present invention provides a light bulb 10 , the light bulb 10 mainly includes a base 100 , a light emitting unit 200 and a lens unit 300 .

[0030] The base 100 is used for receiving external power input. In this embodiment, the base 100 includes a universal connection mechanism 110, the universal connection mechanism 110 is used to adjust the irradiation angle of the light bulb 10, especially to adjust the focused irradiation angle, such as image 3 shown, which shows the figure 2 A usage state diagram of an adjusted irradiation angle of the medium bulb 10 .

[0031] The light emitting unit 200 is disposed on the base 100 for providing light. The light emitting unit 200 includes at least one light emitting diode. In this embodiment, the light emitting unit 200 is indirectly disposed on the base 100 by being disposed on the universal connection mechanism 110 .

[0032] The lens unit 300 is disposed on the base 100 through the...

Embodiment 3

[0036] see Figure 4 , the embodiment of the present invention provides a light bulb 20 , the light bulb 20 includes a base 400 , a light emitting unit 500 , a universal connection mechanism 600 , a light guide assembly 700 and a lens unit 800 .

[0037] Wherein, the base 400 is used to receive external power input; the light-emitting unit 500 is set in the base 400 to provide light, and the light-emitting unit 500 includes at least one light-emitting diode; the universal connection mechanism 600 is set in the base On the seat 400, it is used to adjust the irradiation angle of the bulb 20, especially to adjust the irradiation angle of the concentrated light; the light guide assembly 700 transmits the light to the lens unit 800, and the lens unit 800 includes a flood lens 810 and a The condenser lens 820, the floodlight lens 810 and the condenser lens 820 are integrally arranged, for example, can be integrally arranged by means of bonding, screwing and insert injection molding,...

Abstract

The invention discloses a bulb, which comprises a substrate, a luminescence unit and a lens unit, wherein the luminescence unit is arranged on the substrate and is used for providing ray; the lens unit comprises a floodlight lens and a spotlight lens; and the ray is refracted by the floodlight lens and the spotlight lens to form floodlight and spotlight. In addition, the invention also discloses a lens unit. In the above mode, the bulb and the lens unit thereof disclosed by the invention combine floodlight and spotlight into a whole. The bulb and the lens unit disclosed by the invention have the advantages of simple structure, low cost, high light source use ratio, practicality and reliability.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a light bulb integrating floodlight and light concentrating and a lens unit thereof. Background technique [0002] Lighting is an integral part of people's daily life, creating good visibility and a comfortable and pleasant environment for people. [0003] Some settings, such as museums, require extensive use of flood and spot lights. Floodlight gives people a wide and comfortable feeling without dark bands. The spotlight makes the illuminated object have a sense of being valued / realized. [0004] However, lighting devices in the prior art generally only have a single lighting mode, either a flood lighting mode or a spotlight lighting mode. If the effect of both floodlight and spotlight is to be achieved on a certain occasion, more than two sets of lamps are usually used to complete it. However, the use of two sets of lamps has the problems of wasting power supply, complicated ...
