Embodiment approach 1
[0014] Implementation mode one: if figure 1 As shown, the high luminous rate flashlight includes a flashlight housing 1 , a power supply, a light bulb, a circuit board and a control switch, which includes a light diffusing device 2 externally placed on the top of the flashlight housing 1 . With such a design, by adding the light diffusing device 2 externally placed on the top of the flashlight housing 1, the original weak light is brightened, and the luminous efficiency is improved.
[0015] The light-diffusing device 2 includes a closed transparent lampshade 3 and a light-transmitting agent 4, and the light-transmitting agent 4 is contained inside the closed transparent lampshade 3. In such a design, by adding the transparent lampshade 3 filled with the light-transmitting agent 4 as a new type of light-diffusing device 2, the The original weak light becomes very bright, the luminous efficiency is high, and the entire external light can reach 40 watts; as an optimization, the ...

The invention relates to a flashlight with high luminance. According to the existing flashlight, a silver reflective plastic cover is used for dispersing light, so the luminance efficiency is lower, the light is dimmer, and the brightness is limited. The flashlight with high luminance comprises a flashlight casing, a power supply, a bulb, a circuit board, a control switch and a light dispersing device, wherein the light dispersing device is externally arranged on the top part of the flashlight casing, the light dispersing device comprises a sealed transparent light shade and a light transmission agent, the light transmission agent is accommodated into the sealed transparent light shade, the sealed transparent light shade comprises an outwards protruded smooth curved surface, the smooth curved surface is connected with a cylindrical curved surface to integrally form a rod shape, a connecting piece is arranged between the sealed transparent light shade and the flashlight casing, and the connecting piece is fixedly arranged on the flashlight casing through a plurality of clips. The flashlight with high luminance has the advantages that the transparent light shade accommodated with the light transmission agent is added to be used as the novel light dispersing device, so the original dimmer light is changed into brighter light, the luminance efficiency is higher, and the transparent light shade is widely applied to flashlights of various types.
Description
technical field [0001] The invention relates to a flashlight, in particular to a flashlight with high luminous rate. Background technique [0002] In the prior art, most of the old-fashioned flashlights follow the rules and adopt ordinary designs. The light diffusion method uses a very traditional silver reflective plastic cover to work. The luminous efficiency is low, the light is weak, and the brightness is limited. It is very inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is how to overcome the above-mentioned defects of the prior art, and provide a new type of light-diffusing device by adding a transparent lampshade filled with a light-transmitting agent, so that the original weak light becomes very bright and has the function of concentrating light. And expand the effect of light source area, high luminous rate flashlight with higher luminous efficiency. [0004] In order to solve the above-mentione...
